I decided to buy a climate control assembly both as a spare, and to have spare *****. The ***** look good on the outside, but I found on the back that one **** had a crack starting, but it had not gone far enough yet to split the face of the ****.
My first thought was to put a spring metal ring around the outside of the **** shaft, but it's oblong and that wouldn't work. I decided to epoxy the shaft adding thread reinforcement wrapped around it. I used a strong upholstery thread and super glued the the first loop knot to the shaft.
I mixed up some J-B Weld original formula and applied it to the **** shaft. I then wrapped the shaft with the thread and covered that with a little more epoxy. I added a little bit of epoxy down at the base where the cracks would split out onto the face surface of the ****.
I plan to do all my Crossfire ***** to protect them.
The cracks are caused by internal stresses from the moulding process and irregular shapes concentrate the stress at one or more points.
I doubt that this will stop the cracks as the forces are considerable.
A slow cool down after moulding relieves stresses, but often the part distorts too much.
